Authorities said Reuben and Andrew Fish were arrested after Adam Pacheco's body was found on Saturday. Investigators said Andrew Fish shot and killed Pacheco in a home in McLoud before dumping his body in a dam.

"The victim and Andrew Fish and a third individual were actually seen walking a couple blocks from here," said Pottawatomie County District Attorney Richard Smothermon. "It was late at night. The officer just made contact with them and documented their names and thought nothing of it until we made the phone call."

Police said authorities spotted the Fish brothers and Pacheco walking around in McLoud. When officers went to the home where they said the shooting happened, they found blood on the side of a truck.

Officers arrested both men inside the house. No motive is known for the shooting.
